- Description
- Epithelial-mesenchymal transition (EMT) is an initiating event in tumor cell invasion and metastasis that contributes to therapeutic resistance to compounds including cisplatin. MicroRNAs (miRNAs) have been associated with EMT as well as resistance to standard therapies. However, the underlying mechanisms by which miRNAs control the development of resistance to cisplatin (DDP), and the accompanying EMT-like properties are required to elucidate. Here we show that microRNA-10b (miR-10b) is up-regulated in HNE1/DDP cells, and inhibition of miR-10b expression reversed the EMT phenotype. However, over-expression of miR-10b was able to promote the acquisition of an EMT phenotype in HNE1 cells. Additionally, we identified that miR-10b expression inversely correlates with KLF4, which then controls expression of Notch1. Knock-down of Notch1 inhibited cell migration, invasion, and reversed EMT in HNE1/DDP cells, which was dependent on miR-10b. In summary, our results reveal that miR-10b regulates EMT by modulating KLF4/Notch1/E-cadherin expression, which promotes invasion and migration of nasal pharyngeal carcinoma cells.
